(hennemusic) Twisted Sister have released an online video clip previewing a new live package, "Metal Meltdown", which captures the band in concert in Las Vegas, NV in 2015.

Due July 22 and directed by Brian Lockwood (Bon Jovi, Metallica, Motley Crue), "Metal Meltdown - Featuring Twisted Sister Live At The Hard Rock Casino - Las Vegas" presents the group's complete concert, as well as Rockshow, a bonus documentary that takes fans through the band's 40-year career.

The May 30, 2015 concert with Twisted Sister, Extreme, Great White and Skid Row marked the first event in the Metal Meltdown concert series. The show was dedicated to the honour of drummer A.J. Pero, who passed away two months earlier at the age of 55 from a heart attack while playing on tour with Adrenaline Mob; the group brought in Mike Portnoy to handle drum duties and the rocker made his Twisted Sister live debut at Metal Meltdown.

"The decision to continue performing all the summer shows in 2015, not to mention the concert that this performance celebrates, was in jeopardy over the days immediately following A.J.'s sudden death," explains guitarist Jay Jay French. "We needed time to re-group and re-focus. Everyone was great. All the promoters of the huge European summer festivals that we were set to headline and Barry, the producer of this concert said, 'We understand. You all (meaning the band) have to do what makes you comfortable. Whatever the band decides has to be honoured and respected.'

"In the end, I believe we did what A.J. would have wanted us to do and Mike Portnoy was a very big part of that decision in both an emotional and artistic way. This performance captured herein just two months after A.J.'s death really was about our way to help memorialize the great A.J. Pero.

"The front four (Dee, Eddie, Mark and I) have had no one but A.J. behind us since 1982. This concert has A.J.'s influence permeating through our bloodstream in ways that I will never forget and when we cut to A.J.'s drum solo on the rear projection screen, we were all emotionally overwhelmed. Not since our reunion for NY Steel in 2001 (to honour and raise money for the families of the NYC police and fire department who died on 9/11) have I been moved to tears." Watch the video here.
